Our pup will be coming home on or after March 15th. I read so many bad cases with dogs and kids and actually my son was bit by a foster boxer this past summer. My kids are 5 1/2 Boy(he was the one bit in the face....he was about three feet from the dog when the bit happened, I was right there....the dog just jumped up an bit him....he was evaluated through the boxer rescue and decided they could not adopt him out so he was put to sleep sadly, he had some major issues and a sad past that we were not informed of) 4 1/2 girl, and 2 1/2 year old twin boys. How do I go about the first few days,months,etc of their interactions? I will never leave them alone of course. But how much interaction is okay? Should the older kids help in training? Any other info is appreciated.
